Frequently Asked Questions

Answers to the most important questions about our services

Every project starts with a free initial consultation where we discuss your requirements. We then create a detailed proposal. Once commissioned, we work in iterative phases: concept, design, development and testing. You receive regular updates and can provide feedback at any time. After launch we support you with maintenance and ongoing support.

The duration depends on the scope of the project. A simple website can be completed in 2–4 weeks, a web app in 4–8 weeks, while more complex applications or mobile apps may take several months. After an initial conversation we will put together a realistic timeline for you.

Every project is individual, so we create tailored quotes. A simple website starts at around €2,000, web apps from €5,000. Use our cost calculator for a first estimate or contact us for a no-obligation conversation.

No, not at all! We explain everything in plain language and guide you through the entire process. You only need to know what you want to achieve – we take care of the technical part.

Our payment model is based on project size: for smaller projects (up to €5,000) we work with 50% upfront and 50% upon completion. For medium-sized projects we split into 40% upfront, 30% after the development phase and 30% after final acceptance. For larger projects we offer individual milestone-based payment plans.

After full payment, all rights to the developed code belong to you. You receive the complete source code and can freely use it, develop it further, or have it adapted by other developers.

Yes! Every project includes 1 year of maintenance and support. This covers regular updates, security patches, bug fixes and technical support. Afterwards we offer flexible extension packages.

Of course! Although we are rooted in the Wilhelmshaven and East Frisia region, we work with clients throughout Germany. Thanks to modern communication tools, remote collaboration works smoothly.

Absolutely. We handle both the development of new projects and the modernisation and extension of existing systems. We first analyse your current solution and develop a suitable strategy.

Minor adjustments are covered in the first year by our included support. For larger extensions or new features we are happy to create a separate quote. We are there for you long-term even after the project is completed.
